MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Dec. 25, 1917.

Application filed May 15, 1914. Serial No. 838,773.

To all whom it may concern:

Be it known that I, EMORY M. BARNES, citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented certain new and useful Improvements in Music -Leaf Turners, of which the following is a specification.

This invention relates to music leaf turners and has especial reference to that type in which a music sheet may be turned in either direction by the actuation of a foot pedal, a description of which will subsequently apear. p An object of this invention resides in the provision of a leaf clamp with which is associated suitable means for facilitating the turning of the leaf.

A further object resides in the provision of a device of this character which is simple of construction, in view of its few component parts, eiiicient in its operation, and at the same time inexpensive to manufacture.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings:

Figure 1 is an elevation of the device constructed in accordance with my invention illustrating the application thereof;

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1; and

Fig. 3 is a detail enlarged perspective view of the music leaf clamp and means for facilitating the turning of the same.

In the drawings wherein is illustrated the preferred embodiment of this invention, in order to properly illustrate the application thereof, I have shown a piano, although it is to be understood that any analogous musical instrument may be used, if desired.

The leaf turner in the present instance comprises a plurality of clamp members 5 each of which is formed from a single sheet of metal and has the sides thereof turned downwardly into parallelism with each other, so as to provide a clamp U-shaped in cross section, each of said clamps being provided with ears 6 on one face thereof, which are adapted for engagement with one end 7 of the actuating rod or bar 8. Each of said bars or rods has the opposite end thereof in thereof turned at right angles to the body, 1

and the extreme end which is engaged with the ears 6 of the clamp member 5 turned in parallelism with the body portion 8, while the opposite end thereof is turned at right angles to the body, and in parallel relation to the right angled end 12. Each of said rods is in engagement with the piano or other instrument with which the same are associated, through the medium of eye bolts, staples, or any other suitable securing means as indicated at 13, and has engagement with said rod adjacent the angled end 12 thereof, the opposite end adjacent the angled portion thereof being secured to the front board of the piano through the medium of a similar securing means as indicated at 1 1. Each of said links 9 are preferably of an arcuate configuration, a pair of each being pivotally engaged with the lower angled end of each of said rods 8, as previously pointed out, one of said links being pivoted above, and the other below said angled end, and adapted to actuate thereover when pressure is exerted on the actuating treadle with which it is in engagement beneath the piano. Each of said cables which is engaged with one of the links 9, at one end, and with the actuating treadle 11 at the opposite end thereof, are trained over rollers 15, the latter being journaled in suitable frames 16, one of which is fixedly carried on a portion of the piano above the key board, while another one is secured to each side of the piano, as advantageously illustrated in Fig. 1, said rollers being provided in order to facilitate the operation of the cables 10 for turning the sheets of music with which the clamps 5 are in engagement.

In order to facilitate the turning of the music sheets, I have connected to each of the clamp members 5, a strand of wire 17 which is preferably of a semicircular configuration, and has formed on the extreme end 18 thereof a book which is adapted for engagement with the longitudinal edge of the music-sheet, in order to insure the positive turning of the sheet of music when pressure is exerted on one ofthe pedals 11. Each of the wires 8 has the one end thereof secured to the clamp 5 adjacent the ears 6 thereof as shown to advantage in Fig. 3, as at this point a better-leverage is obtained for facilitating the turning of the music leaf.

In operation the clamps 5 are engaged with the upper edge, of the music sheets, and the wires 17 engaged beneath said sheets, the hook end 18 of each of said wires being engaged with the longitudinal edge of the sheet with which it is associated. Assuming that the device is in engagement with music sheets, as shown to advantage in Fig. 1, should it be desired to turn the music leaf, pressure is exerted on one of the pedals 11, on the left side of the piano according to the clamp member which is in engagement with the music sheet, causing the same to be turned to the opposite side. Should it be desired to return the same sheet, to the position shown in Fig. 1 pressure is exerted on one of the pedals 11 on the right side of the piano thereby. drawing the cable which is associated therewith taut and causing one of the clamps 5 which is actuated by this cable to be actuated for turning the music sheet to its original position. From the above it is obvious that the sheets may be readilyand easily turned by the mere actuation of one of the foot pedals as above described.

It will be understood that the above description and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement of parts, may be made within the scope of the appended claim and without sacrificing any of the advantages-of my invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

In a music leaf turner, an upright lea t' turning rod having its upper end disposed angularly thereto forming an arm, said rod having an integral reduced arcuated leafsupporting member depending from said arm, and a two part leaf-clamping member, the proximate portions of which are hinged together and secured to the upper end of the leaf-supporting member, the sides of said two part clamping member embracing the latter.

In testimony whereof I ailix my signature in presence of two witnesses.

EMORY M. BARNES.
